Over the past six years, my laboratory, and others, have been conducting research focused on identifying bioactive plant compounds (known as phytochemicals or phytonutrients) and evaluating the biological effects of maple syrup, maple water (i.e. maple sap), and maple plant parts and their derived extracts.
We found significant populations of snake worms devouring the organic matter, causing soil conditions that discouraged growth of understory native plant species. We are looking at their distribution in maple stands throughout the region relative to forest management practices, and assessing their impact on understory diversity, maple regeneration and various soil characteristics.
The purpose of the present experiment was to test the precision of a variety of digital refractometers available to maple producers. Additionally, the effect of temperature on refractometer accuracy and precision was investigated, in order to assess the reliability of the automatic temperature compensation feature now present in the majority of refractometers.

This research shows the trends in bulk syrup prices in the U.S. and Canada between 1998 and 2015.
Organizations grow and develop like children, animals or plants. Understanding organizational growth can help make sense of what is happening in maple producer organizations.
Some have questioned the accuracy of NASS’s Maple Syrup estimates. The most common criticisms typically include: some producers don’t return their report, some don’t report accurately, and some don’t receive a report. I will address each one separately.
Between 2008 and 2011 we conducted a series of controlled experiments performed with commercial maple equipment to investigate the potential effects of the use of RO on the composition, properties, and flavor of the maple syrup produced.
This research shows trends in sap yield in US states and Quebec from 2001-2014.
Sugar maple (Acer saccharum Marsh.) decline disease, decreased growth, and regeneration failure have been related to a low supply of Ca and Mg. There is increased interest in augmenting cation availability via liming, but there is little information on the amounts of lime required and the longevity of the lime treatment. A single application of 22.4 Mg ha-1 of dolomitic limestone in 1985 at four forested sites in Potter County, PA has shown that soil, soil water, and sugar maple foliage chemistry are significantly altered by liming and the changes in soils and foliage persist as long as 21-yr post-treatment. By 2001, only 3 kg ha-1 of lime remained undissolved while increases in exchangeable Ca and Mg, and pH continued through 2006 at depths up to 35 to 45 cm.
